 The asterisk ("*", ASCII 2A hex) and exclamation mark ("!" , ASCII 21 hex)
 are reserved for use as having special significance within specific
 schemes. Source:

 More here: https://developers.google.com/maps/url-encoding

 WordPress however, redirects to a URI encoded variant when the query
 string at the root level contains these reserved characters.

 So, https://wordpress.org/plugins/?test=123*456 doesn't redirect.

 While https://wordpress.org/?test=123*456 redirects to
 https://wordpress.org/?test=123%2A456.

 This is quite problematic for all WordPress sites that use for example
 Google Analytics 4 (GA4) cross-domain tracking. GA4 relies on a query
 string containing asterisks. Source:
